Замечания

The class uses a WMIConn connection to connect to a server, execute a Windows Management Instrumentation Query Language (WQL) query against it, and return the results. The WQL query can either be provided directly, or a variable or file connection can be used to dynamically provide WQL queries at execution time.

Similarly, this class can use either a file connection or variable to receive the results of the WQL query. The output type of the WQL query results can also be specified.
